§  73.691   Visual modulation monitoring.

   (a) Each TV station must have measuring equipment for determining that
   the transmitted visual signal conforms to the provisions of this
   subpart. The licensee shall decide the monitoring and measurement
   methods or procedures for indicating and controlling the visual signal.

   (b) In the event technical problems make it impossible to operate in
   accordance with the timing and carrier level tolerance requirements of
   §  73.682 (a)(9)(i), (a)(9)(ii), (a)(12), (a)(13), and (a)(17), a TV
   broadcast station may operate at variance for a period of not more than
   30 days without specific authority from the FCC: provided that, the
   date and time of the initial out-of-tolerance condition has been
   entered in the station log. If the operation at variance will exceed 10
   consecutive days, a notification must be sent to the FCC in Washington,
   D.C., not later than the 10th day of such operation. In the event
   normal operation is resumed prior to the end of the 30 day period, the
   licensee must notify the FCC upon restoration of normal operation. If
   causes beyond the control of the licensee prevent restoration of normal
   operation within 30 days, a written request must be made to the FCC in
   Washington, D.C., no later than the 30th day for such additional time
   as may be necessary.
